Integrated pest management of Tuta absoluta: practical implementations across different world regions

The South American tomato pinworm, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae), has invaded most Afro-Eurasian countries and is threatening worldwide tomato production. Various strategies have been developed and implemented to manage this pest. Here, we present a timely review on the up-to-date development and practical implementation of integrated pest management (IPM) programs for tomato crops across different world regions infested by T. absoluta. While insecticide resistance is a growing concern, biological control via releasing or conserving arthropod natural enemies and sex pheromone-based biotechnical control are the most successful management practices. Agronomic control-related research is an emerging area where the soil fertilization and/or irrigation, as well as breeding of resistant cultivars, has the potential to enhance IPM effectiveness. Grower survey responses in the native areas (i.e., South America), early-invaded areas (i.e., first report between 2006 and 2012) and newly invaded areas (i.e., first report after 2012) showed that the control programs evolved along with the areas and time since invasion. Growers in the early-invaded areas shifted more rapidly from chemical control to biological control compared to those from the native area. In all concerned regions, the pest control failure risk following chemical insecticide applications and the high cost associated with either biological or biotechnical control methods have been the greatest concerns for growers. The information gathered from the native and/or early-invaded areas may help achieve a more effective management in newly invaded areas. Lastly, researchers are expected to break the bottlenecks of some key issues that would enable lowering application cost of novel biorational alternative management options

However, data relating to the mean platelet volume (MPV) in patients with panic disorder (PD) are both limited and controversial. Herein, we aimed to evaluate, for the first time, the red cell distribution width (RDW) levels combined with MPV levels in patients with PD.Patients and methods: Between January 2012 and June 2015, data of 30 treatment-naïve patients (16 females, 14 males; mean age: 37±10 years; range: 18–59 years) who were diagnosed with PD and 25 age- and sex-matched healthy volunteers (10 females, 15 males; mean age: 36±13 years; range: 18–59 years) (control group) were retrospectively analyzed. The white blood cell count (WBC), MPV, and RDW levels were measured in both groups.Results: The mean WBC, MPV, and RDW levels were 9,173.03±2,400.31/mm3, 8.19±1.13 fl, and 12.47±1.14%, respectively, in the PD group. These values were found to be 7,090.24±1,032.61, 6.85±0.67, and 11.63±0.85, respectively, in the healthy controls. The WBC, MPV, and RDW levels were significantly higher in the patients with PD compared to the healthy controls (P=0.001, P=0.001, and P=0.003, respectively). However, there was no significant difference in the platelet number between the patients with PD and healthy controls (P>0.05).Conclusion: Our study results are the first to demonstrate that the RDW levels combined with MPV levels significantly increase among patients with PD. We believe that increased RDW and MPV levels can be used as a novel marker for PD. Keywords: panic disorder, mean platelet volume, red cell distribution width, white blood cell count, platelet numbe

A novel marker to predict cardiac arrhythmia in epilepsy patients: frontal QRS-T angle

OBJECTIVE: The most important complication of epilepsy, which is a chronic disorder of the central nervous system, is sudden unexplained death in epilepsy (SUDEP). The causes of SUDEP are complex and multifactorial. Epilepsy patients are at increased risk of cardiovascular events, SUDEP, and ventricular arrhythmias, due to both the disease itself and the effect of antiseizure medications. Previous studies have commonly focused on cardiac repolarization markers in epilepsy patients. This study aimed to investigate frontal QRS-T angle (FTQ angle), a relatively new repolarization parameter, in epilepsy patients. PATIENTS AND METHODS: One hundred two epilepsy patients and 86 healthy volunteers as a control group were included in the study. The clinical data of all patients were prospectively recorded during patient visits. All participants underwent 12-lead surface electrocardiography (ECG). SPSS 22 was used to evaluate all data. p<0.05 was considered statistically significant. RESULTS: When the epilepsy patient group and the control group were compared in terms of QRS (89.59±43.63 vs. 80.00±9.82, p=0.050), QT (364.30±36.16 vs. 335.95±35.64, p<0.001), QTc (418.85±27.06 vs. 409.37±26.66, p=0.018) durations, and FTQ angle (46.55±22.06 vs. 20.84±12.70, p<0.001), statistically significant differences were found between the groups. We observed that FTQ angle was significantly higher in individuals exposed to the disease for more than 10 years (39.2±19.0 vs. 54.7±22.5, p<0.001). In addition, according to the multivariate logistic regression analysis, disease duration was an independent predictor of FTQ angle (β=0.263, p=0.009). CONCLUSIONS: FTQ angle, a relatively new repolarization parameter, can be used as an inexpensive, easy, reproducible, and reliable ECG marker to predict the risk of adverse cardiac events in epilepsy patients

Yield and quality criteria in organically and conventionally grown tomatoes in Turkey Produção e qualidade de tomates cultivados sob sistemas orgânico e convencional na Turquia

The term 'organically grown food' denotes products that have been produced in accordance with the principles and practices of organic agriculture. The use of alternatives to synthetic fertilizers is an important issue in organic systems. A two-year field experiment to evaluate effects of organic fertilizers on the yield and quality of open field grown tomatoes (Lycopersicon esculentum Mill.) was carried out in Southern Turkey in 2000 and 2001. Combinations of manure, blood flour and micronutrient preparations were used for fertilization, and conventional mineral fertilization was included as the control. Yield did not differ between the fertilization and the Conventional treatments in the first year of the study, but the highest yield was obtained from conventional in the second year. No differences were found between treatments in terms of fruit soluble sugar content or citric acid. The application of organic fertilizers positively affected the micronutritional element content of tomato fruits compared to the conventional treatment. Organic fertilization results in improved yield and fruit quality compared to conventional fertilization. In addition, organic fertilization should be supported in order to facilitate reuse and disposal of organic wastes and to maintain and/or increase soil fertility.<br>O termo "alimentos cultivados organicamente" denota produtos que tenham sido produzidos em conformidade com os princípios e práticas da agricultura orgânica. O uso de alternativas para fertilizantes sintéticos é uma questão importante em sistemas orgânicos. Um experimento de campo foi conduzido no sul da Turquia em 2000 e 2001 para avaliar os efeitos da adubação orgânica na produtividade e na qualidade de tomates (Lycopersicon esculentum Mill), cultivados em campo aberto. Combinações de esterco, farinha de sangue e preparações de micronutrientes foram utilizados para a fertilização, e adubações minerais convencionais foram incluídas como controle. A produção não diferiu entre a fertilização e os tratamentos convencionais no primeiro ano do estudo, porém uma maior produtividade foi obtida a partir do sistema convencional, no segundo ano. Não foram encontradas diferenças entre os tratamentos em termos de teor de açúcares solúveis ou ácido cítrico em frutos. A aplicação de fertilizantes orgânicos afetou positivamente o conteúdo dos elementos micronutritionais dos frutos do tomateiro em relação ao tratamento convencional. A adubação orgânica resultou em maior produtividade e qualidade dos frutos, quando comparada à adubação convencional, e deve ser apoiada, a fim de facilitar a reutilização e eliminação de resíduos orgânicos bem como para manter e/ou aumentar a fertilidade do solo

Treatment delays and in-hospital outcomes in acute myocardial infarction during the COVID-19 pandemic: A nationwide study

Objective: Delayed admission of myocardial infarction (MI) patients is an important prognostic factor. In the present nationwide registry (TURKMI-2), we evaluated the treatment delays and outcomes of patients with acute MI during the Covid-19 pandemic and compaired with a recent pre-pandemic registry (TURKMI-1). Methods: The pandemic and pre-pandemic studies were conducted prospectively as 15-day snapshot registries in the same 48 centers. The inclusion criteria for both registries were aged ≥18 years and a final diagnosis of acute MI (AMI) with positive troponin levels. The only difference between the 2 registries was that the pre-pandemic (TURKMI-1) registry (n=1872) included only patients presenting within the first 48 hours after symptom-onset. TURKMI-2 enrolled all consecutive patients (n=1113) presenting with AMI during the pandemic period. Results: A comparison of the patients with acute MI presenting within the 48-hour of symptom-onset in the pre-pandemic and pandemic registries revealed an overall 47.1% decrease in acute MI admissions during the pandemic. Median time from symptom-onset to hospital-arrival increased from 150 min to 185 min in patients with ST elevation MI (STEMI) and 295 min to 419 min in patients presenting with non-STEMI (NSTEMI) (p-values <0.001). Door-to-balloon time was similar in the two periods (37 vs. 40 min, p=0.448). In the pandemic period, percutaneous coronary intervention (PCI) decreased, especially in the NSTEMI group (60.3% vs. 47.4% in NSTEMI, p<0.001; 94.8% vs. 91.1% in STEMI, p=0.013) but the decrease was not significant in STEMI patients admitted within 12 hours of symptom-onset (94.9% vs. 92.1%; p=0.075). In-hospital major adverse cardiac events (MACE) were significantly increased during the pandemic period [4.8% vs. 8.9%; p<0.001; age- and sex-adjusted Odds ratio (95% CI) 1.96 (1.20-3.22) for NSTEMI, p=0.007; and 2.08 (1.38-3.13) for STEMI, p<0.001]. Conclusion: The present comparison of 2 nationwide registries showed a significant delay in treatment of patients presenting with acute MI during the COVID-19 pandemic. Although PCI was performed in a timely fashion, an increase in treatment delay might be responsible for the increased risk of MACE. Public education and establishing COVID-free hospitals are necessary to overcome patients' fear of using healthcare services and mitigate the potential complications of AMI during the pandemic. © 2020 by Turkish Society of Cardiology
